[Problem] To provide a compound which can be used for the prevention and/or treatment of diseases in which 5-HT
2B
receptor and 5-HT

receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[Means for Resolution] It was found that an amide derivative characterized by the possession of a nitrogen-containing bicyclic hetero ring (e.g., an indole or the like), or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT
2B
receptor and 5-HT

receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT
2B
receptor and 5-HT

receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[问题] 提供一种可用于预防和/或治疗与5-HT2B受体和5-HT7受体有关的疾病的化合物,特别是用于治疗肠易激综合征(IBS)。
[解决方法] 发现一种具有含氮双环杂环(例如吲哚或类似物)的酰胺衍生物或其药学上可接受的盐具有强烈的5-HT2B受体和5-HT7受体的拮抗作用。此外,本发明的化合物具有对两种受体的拮抗活性,与仅使用选择性拮抗剂相比,表现出良好的药理作用。基于上述,本发明的化合物可用于预防和/或治疗与5-HT2B受体和5-HT7受体有关的疾病,特别是用于治疗肠易激综合征(IBS)。
